  • Title: [Comparison of the Laryngeal Tube Suction and the Proseal laryngeal Mask Airway in anesthetized patients].
    Author: Ueno M, Suzuki A, Takahata O, Iwasaki H.
    Journal: Masui; 2008 Sep; 57(9):1131-5. PubMed ID: 18807900.
    Abstract:
    BACKGROUND: The Laryngeal Tube Suction (LTS : Smith Medical, Tokyo) is a new laryngeal tube that has an additional channel for gastric tube placement. Similarly, the Proseal Laryngeal Mask Airway (PLMA) also has a drain tube for gastric tube placement. This study compared the functions of these two devices. METHODS: Forty patients undergoing general anesthesia were randomly allocated to the group LTS (n = 20) or group PLMA (n = 20). Ease of insertion, quality of airway seal, ease of gastric tube insertion, fiberoptic view of the glottis through each device after placement, and postoperative sorethroat/hoarseness were investigated. RESULTS: There were no differences in patient characteristics and anesthetic background data for both groups. No differences concerning handling, quality of airway seal, ease of gastric tube insertion, and postoperative airway morbidity were detected between LTS and PLMA. In economical terms, LTS was more reasonable compared with PLMA. CONCLUSIONS: With respect to clinical function, the LTS and PLMA were similar and either device can be used to establish an effective airway in anesthetized patients.
